Simply the best.
Light, compact, ultra high performance.
Proton Ice is a powerhouse of technology and innovation for those seeking great reliability and high performance in a regulator that is exceptionally compact and lightweight. Proton Ice offers demanding divers all the features that have made Mares regulators famous around the world, in a product with an all-new design, completing the Proton range.
First stage
The Proton XL is equipped with the brand new V32 first stage, which immediately sets it apart with its distinctive aesthetics and exceptional light weight for a first stage of this class. Diaphragm operation and DFC system. The forged brass body with chrome and nickel plated finish is protected by a shockproof and scratch-resistant coating. The high pressure valve features the SCS spherical seal system, for superior durability. The high and low pressure ports are positioned for optimal hose routing and maximum diving comfort.
Second stage
The most compact metal second stage in the world. Thanks to the integrated VAD system, it offers top-level performance that vastly exceeds, not only the requirements for CE certification, but the stringent U.S. Navy specifications as well. Thanks to its “all metal” technology, it is also ideal for diving in very cold water. Indeed, a unique and revolutionary design. The oversized purge button is extremely easy to use, even while wearing thick neoprene gloves. The “mesh grid” system minimizes the likelihood of free-flow in strong currents. The new design exhaust tee, with its streamlined shape, affords superior performance while directing air bubbles further away from the face.
